福立GC-9用5m*3mm的GDX-502甲烷柱

名称：甲烷柱

固定相：高分子小球

粒度：60-80目

规格：5m*3mm

型号：GDX-502

应用：环境空气/固定污染源废气/总烃，甲烷，非甲烷总烃的测定  气相色谱法

现阶段，挥发性有机物（VOCs）被社会各界予以高度关注，因为它是复合型大气污染的重要诱因。石油炼制企业以非甲烷总烃（NMHC）作为VOCs排放的控制指标。为有效管控VOCs，非甲烷总烃的精密度非常重要，而提高测定的精密度则是非甲烷总烃精密度的前提。

浩瀚色谱（山东）应用技术开发有限公司，，针对国标采用2m的GDX-502不能完全分离氧和甲烷的现实情况，研发5m*3mm的GDX-502作为甲烷柱，在福立GC9上完成测试，氧和甲烷完全分离，无干扰，效率高，结果满意。

5m*3mm GDX-502 methane column for Fuli GC-9 Details:

Name: Methane column

Stationary phase: polymer beads

Granularity: 60-80 mesh

Specifications: 5m*3mm

Model: GDX-502

Application: Determination of ambient air/stationary pollution source waste gas/total hydrocarbons, methane, non-methane total hydrocarbons by gas chromatography

At this stage, volatile organic compounds (VOCs) are highly concerned by all sectors of society because they are an important cause of complex air pollution. Petroleum refining enterprises use non-methane total hydrocarbons (NMHC) as the control index of VOCs emission. In order to effectively control VOCs, the precision of non-methane total hydrocarbons is very important, and improving the measurement precision is the premise to ensure the precision of non-methane total hydrocarbons.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. keeps pace with the times. In view of the fact that the national standard 2m GDX-502 cannot completely separate oxygen and methane, it develops 5m*3mm GDX-502 as a methane column. The test was completed on the above, oxygen and methane were completely separated, no interference, high efficiency, and satisfactory results.
